I know I can change the source code for FEAT_ARABIC (which is how I do it now) but that's not the way to go for long run in a case vim gets updated. The reason I want to disable them using flags is because I use the 'huge' flag for building the vim from the source. Actually someone suggested this flag a year ago using a patch but it didn't went through:

You are missing something. You can build Vim with the Arabic and/or
Farsi feature, but so long as you don't set the 'arabic' or 'fkmap'
options then nothing should be different. You haven't answered the
question why anything changes without setting those options. I always
build with huge features and don't get any Arabic stuff because it's not
enabled by the option.
